Wheel Chair Ramp Standards

Wheelchair ramps vary greatly. Some ramps are so steep, using them is difficult and dangerous. Other ramps are too narrow and some dangerously uneven. Though often ignored, wheelchair ramp standards exist and should be complied with for the safety of those using the ramps.

Ramp

• A wheelchair ramp takes the place of stairs. The ramp allows those using wheelchairs and those with walking difficulties the ability to navigate up an incline from one level to another. Although wheelchair ramp standards may differ, in some respects, from one place to another, the Americans with Disabilities Act offers Accessibility Guidelines. Ramps may be permanent, portable or semipermanent.

Specifications

• A wheelchair ramp should be no narrower than 3 feet wide or it won't be wide enough to maneuver a wheelchair up the incline. For every foot of length, a new ramp construction should rise 1 inch, though older ramps are allowed a 1:16 to 1:20 ratio. More slope and the ramp becomes too steep; less slope and too much length may be required for the space/height available. Landings need to be incorporated at the beginning and end of each ramp section, none of which should be longer than 30 feet.

Handrails

• Wheelchair ramps need sturdy handrails on both side. For adults, these should be 30 to 34 inches above the ramp and at least 1 and 1/2 inches from the wall.
